Epoxy and glass composites in water studied with 2H-NMR.

Abstract:

The amt., behavior, and localization of water in epoxy resin composites largely influence the mech. properties and aging. Gravimetric anal. combined with 2H-NMR of heavy water in epoxy resin-glass fabric composites provides direct information about types of water, which can be distinguished by their mobility. Three different epoxy composites were analyzed with this technique. The results are correlated with mech. properties.
